Here is my current GPT/MBR partition table:
Current GPT partition table: # Start LBA End LBA Type 1 40 409639 EFI System (FAT) 2 409640 663646255 Mac OS X HFS+ 3 663646256 664915791 Mac OS X Boot 4 664915968 1164914687 Basic Data 5 1164914688 1169649663 Linux Swap 6 1169649664 1465149134 Unknown Current MBR partition table: # A Start LBA End LBA Type 1 1 409639 ee EFI Protective 2 409640 663646255 af Mac OS X HFS+ 3 663646256 664915791 ab Mac OS X Boot 4 * 664915968 1164914687 07 NTFS/HPFS
The above is information I got from the 'Partition Inspector' on Mac OS X. Here is the situation:
Partition2: I have Mac OS X 10.7 installed Partition4: I have Windows 8 Release Preview installed Partition6: I have Arch installed (without boot loader)
I have rEFIt installed.
This is what I am able to do:
- Boot into Mac and Windows using rEFIt.
- Boot into the Arch setup on my USB drive and chroot into the installed system.
This is what I am not able to do:
- Boot into the installed Arch system and/or install a boot loader.
So what I basically need is to install a boot loader. I followed the instructions given in the Arch manual, but installing both grub-bios and grub-efi-x86_64 is not working.
Installing grub-bios gives an error 'Cannot identify filesystem on /dev/sda' and grub-efi-x86_64 gives an error saying 'Fatal: Couldn't open either sysfs or procfs directories for accessing EFI variables. Try 'modprobe efivars' as root'. I tried
mod probe efivars, but it didn't help the situation. I get the above error when I run the command:
grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=arch_grub --recheck
My basic question is what options do I have to setup my triple boot.. since I am almost there.
PS Is it possible for me to simply boot from rEFIt? Like how I would do it from grub by specifying the root, kernel and initrd parameters?
